Unadjusted Kaplan–Meier curve demonstrating a overall survival, b cancer-specific survival, c local control and d distant control for pre-treatment neutrophil counts of ≤3.2 × 1000 mm3 (blue), 3.2–4.4 × 1000 mm3 (green) and >4.4 × 1000 mm3 (red). Cox-regression UVA reflects pre-treatment neutrophil count as a continuous variable
